Rwandan who also must be heard (4)
I believe the answer is:
hutu
'rwandan who also must be heard' is the definition.
The definition suggests a singular noun which matches the answer.
This is the entire clue.
Can you help me to learn more?
(Other definitions for hutu that I've seen before include "Bantu speaker from Rwanda or Burundi" , "Africans" , "Member of a Bantu people living in Rwanda and Burundi" , "A member of one Rwandan people" , "Rwandan or Burundian" .)
